PAINT REMOVING DEVICE.

Specification of Letters Patent.

Patented Oct. 7, 1913.

Application filed June 7, 1913. Serial No. 772,414.

To all'whom it may concern:

Be'it known that I,"MARKUs L. SPIRA, a

subject of the King of Hungary, residingat Cleveland, in the county ofCuyahoga and State of Ohio,'. have invented certain new and usefulImprovements in Paint-RemovingD'evices; and I hereby -declare thefollowing-to be-a-full', clear, and exact description of the' invention,such as will enable others skilled inthe art to which it pertains tomake and use the same.

This inventionrelates to improvements in paint-removing devices,and'pertains more especially to a paint-removing device employed inremoving paint from wood or metal.

The primary object of this invention is to produce adevice wherebyburned paint can be removed from a painted surface before the burned andconsequently blistered or softened and loosenedpaint has had a chancetoharden;

Another-'objectis to provide a paint removing-device of the characterindicated which can'- be"manufactured with facility at little cost:

Withthese'objects in View, and totheend of attaining-any other advantagehereinaften appearing;this invention consists in certain features ofconstruction, and combinations and arrangement of parts, hereinafterdescribed, pointed out in the claims, and illustrated in" theaccompanying drawings.

In said drawings, Figure 1 is atop plan of' a rail and'shows my improvedpaint-removing" device in position for removing paintfrom one sidesurface of said rail. Fig. 2 is a sectionon'line 2-2, Fig. 1, lookingin'the direction indicated by the arrow, but therail illustrated in Fig.'Tis omitted in" Fig. 2. Fi'gL3-is a central section'of my improvedpaint-removing device and shows the la-tter in the position shown inFig. 1. Fig-'4 is a transverse section on line 4-4, Fig.3, lookingforwardlv.

My improved paint-removing device comprises a-meta-l blade'A forscraping the blisterjed' or burned .and softened or loosened paint froma painted surface. Said blade is adapted to extend transversely of thesurface to be scraped, and in'Fig. l is-sh'own in position fdrscrapingpaint from-one side of the rail C. F ig; 1 showsmy improvedpaint-removing device to be moved in; the: direction indicated" by the*arrow 6'to scrapepaint from-"said rail. The'blade A is provided withtwo forwardly projecting arms a-which, as shown in Fig. 4, are arrangedat opposite ends respectively of the blade. Said arms are thereforespaced longitudi- "nally'of'the blade A and are also spaced from thescraping-edge 7 of the blade. Said arms are connected together by ametal plate ,B. The blade A and the plate B are therefore" connectedtogether, and said plate is adapted toengage with the head D of a paintburning nozzle, and said nozzle and said plate are "removably securedtogether as will hereinafter appear. The plate B and the connected bladeA are preferably composed of a single-metal piece. The arms aareprefer'ably arranged at an obtuse angle to the blade A, and the plateB is arranged substantially at a right angle to and extends rearwardlyfrom said arms. In the position of the paint removing: device shown inFig; 1 to remove paint from aside of .a

rail there is no liability, of course, of scrapedoff paint accumulatingin frontof the blade- A 'because' the scraped-ofl? paint will fall fromthe rail, nor is there any liability of theaccum'ulation of scraped-0Epaint in front of the blade=in scrapingoif paint by a downwardmovement-onthe painted surface, but in scraping-painton an upwardmovement of the'paint-removing device the spacing of-"thearms a will befound not unimportantfto' permit 'escape' of the scrapedofi" paintbetween said arms and thereby prevent any'undue accumulation ofscraped-off paint between the blade A and the forward end I of -'thepaint-burning 1 nozzle.

The nozzle-head ID forms the forward portionpf the nozzle and rojectsforwardly are spaeed'longitudinally' ofsaid edge and form "the outletsof'the chamber 8. Ob;

viousl-y saidedgefor-ms the forward or discharging end of the nozzle. Iwould hererernark that the-nozzle and the blade A are" so relativelyarranged that when the scraping edge 7 of said. blade is incontact withthe painted" surfaceto be scraped the- .frontedge 10 or forward endofthe nozzle isspaced from said surface in the operative position of theblade shown in Fig. 1. The head D of the nozzle is widest at its frontedge 10 or forward end and gradually reduced in width toward its rearend. Said nozzle has a tubular neck 03 which projects rearwardly fromthe rear end of the head D and is arranged centrally widthwise of saidhead. The neck (1 is in communication with the chamber 8 and is employedin conducting the fluid fuel, such, for instance, as gas or gasolene, tosaid chamber. Said neck is shown screw-threaded internally of its outerend,as at 13, and adapted to be connected in any approved manner to' thebody (not shown) of a hand-torch or attached to a flexible tube (no-tshown) leading from a pipe for supplying fluid fuel.

By the arrangement of the parts hereinbefore described it will beobserved that the plate B extends widthwise of the head D and has itsside edges 14 (see Fig. 2) converging rearwardly. The paint-burningnozzle and the plate B are parallel, and said plate is provided at therear end of the head D with a rearwardly projecting arm 6 arrangedlongitudinally of and engaging the neck (1 of the nozzle. Said neck isprovided with any suitable number of apertures 03 which form theair-inlets of the nozzle. Said neck is preferably substantially circularin cross-section, and the arm 6 is curved transversely to conform tosaid neck. The arm 6 is provided centrally between its side edges with aslot 15 extending longitudinally of the arm and hastwo anges 16 arrangedat opposite sides respectively of and extending longitudinally of saidslot and overlapping opposite side walls respectively of a recess 17formed in and extending longitudinally of the neck d of the nozzle. Itwill be observed therefore that the paintburning nozzle is adjustablelongitudinally of the arm (Z,or, in other words, the blade A isadjustable longitudinally of the nozzle,and that the projection of theflanges 16 of the neck 03 of said nozzle and the side walls of therecess 17 prevent displacement of said arm circumferentially of saidneck without interfering with the adjustability of said arm endwise ofsaid neck. As shown in Fig. 2, the flanges 16 are spaced at their endsfrom the ends of the recess 17, and said recess therefore is long enoughto accommodate any desired relative readjustment of the nozzle and theconnected blade A. By the construction hereinbefore described it will beobserved that the plate B and its arm I) constitute a nozzle-engagingmember arranged exteriorly of the nozzle and extending opposite saidrecess; that said nozzleengaging member is connected to the blade A;that said blade is arranged to scrape the burned paint from a paintedsurface operated on by the flames issuing from the orifices 12 of thenozzle during the operaare secured in the desired relative adjustment bya suitably applied bolt E and nut G. As shown in Figs. 3 and 4 the shankof the bolt E extends through the nozzle-neck d' and through the slot 15and has its free end arranged adjacent said slot, and the nut G- isscrewed onto said shank and against the arm I) externally of said slot,and the bolt has a head e formed thereon at the opposite end of saidshank and overlapping the exterior' of the aforesaid neck.
